adjust the cover to fit. I 'A further object is to the operating parts of the machine, and will be automatically held againstany movement in a covering direction. i

A further object of theiinvention is to prov, vide' a cover which may, be locked in its closed position if' desired, so that the-,1na-,;

chine cannot be easily tampered with. The

' cover may also be readily, mountedin connection with any standard typewriter and p M when inplace either inits enveloping or uncoverlng positions will I attractiveyappearance.i

vA further; object of the invention, is to pros duce a simple and inexpensive device-and yet one which will be, exceedingly effective 7 for-the purposeforwhich it is designed.

These objects I accomplish'by means of suchstructure and relative arrangement of parts as will fully appear by a perusal of the erence indicate several Views;

providea device of this character of such a nature that. when it is thrown back to uncover the machine said cover Qwillbe thendisposedso as not to in-. terfere with the necessary manipulation of present a neat and Fig. 4 is an enlarged fragmentary sectional plan taken on the line 4-4 of Fig. 1.

Referring now more particularly to the characters of reference on the drawings,'the numeral l denotes a base plate adapted to be disposed under a typewriter 2 between the front'and rear feet 3 thereof and then extendmg beyond both sides of the typewriter a certain distance.

The plate 1 is adapted to be detaohably but firmly. mounted on the supporting element 4; which also supports the typewriter, by

means of studs 5 arranged to be fixed in and project upwardly from said element through the plate 1 and to be engaged by finger nuts' 6 above the plate. At its sides the plate-1 has upstanding flanges 7 which have longitudinal slots 8 therein.

I Disposed rearwardly of the base plate and behind the typewriter-is a cover supporting structure comprising a Vertical back plate 9 of a'height to extend above the top of the machine and of a width greater than that of said machine; said back plate havingfriangular side wings 10 sloping downwardly and forwardly therefrom to the base plate. Forwardly projecting extensions 11 are attached tothe lower ends of the wings and are slidable between the flanges 7, saidextensions having lateral pins 12 engaging the slots 8 in said flanges.

Projecting toward each other from the forward edges of the wings, and also downwardly from the top of the back plate, is a continuous flange 13,; whose whole extent lies in the same angular plane as the forward edges of thewings. Secured to and projecting forwardly fromthe lower ends of the side anges 13 are rods 14 or the like arranged to form enclosed eyes 0 loops with said flanges. Engaging and turnably mounted on saideyes as an axis is a three sided rectangular frame 15, the exterior dimensions of which are the same as the corresponding dimensions of the back plate and wings. The frames 15 and the flange 13, form the front and back bowsrespectively of a collapsible cover structure 16, and said bows are of double construction so as to enable the opposite ends of said cover to be clamped between the two thicknesses of the bows. The cover structure 16 is of rectangular form, corresponding to the bows and is preferably of the well known bellows or accordion pleat construction; The pleats or folds of the cover are orificed so that the upperlportionsofthe rods-1.4 (which also engagexthebowlld), pass freely therethrough.

The interior size of the bow 15 and of course the cover also is such as to clear all parts of the typewriteri The top bar ofthe bow"15 is provided with an outwardly projecting handle member .17. n

In operation. when not bow is raised and swun'grupwa-rd'lyand rearwardly, a movement which causes the pleats ofi'th'e cover'to 'fo'ld: When the bow; has

With this movement the cover ,16 w-ill beunfolded and will move through a substantially circular arc, owing to the substantially axial connection: of the bow and cover with thej'memb'ers 14.
